Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.560C>T (p.T187I) alteration is located in exon 8 (coding exon 8) of the PTCD3 gene. This alteration results from a C to T substitution at nucleotide position 560, causing the threonine (T) at amino acid position 187 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
